Cape Town - Removable drives are the main source of malware infections facing South Africans, even as cyber crooks target financial information, says a security expert.
"While mobile and financial malware, advanced persistent threats and web threats are becoming more popular among cybercriminals, removable devices and local networks are still the prime sources of IT risks for users in Africa," Ghareeb Saad, senior security researcher with the Global Research & Analysis Team, Middle East, Turkey and Africa at Kaspersky Lab told News24.
He said that the company prevented 49 million cyber attacks in Africa, and around 10% or 4.6 million were in SA.
"The most popular malware used by cybercriminals in the region in the first quarter - the Dinihou Worm - was responsible for approximately three million infections," said Saad.
"It spreads through removable media devices making use of .LNK files. The most frequently exploited vulnerabilities were breaches in VLC Media Player. There were also numerous incidents of security holes in Oracle Java being exploited in South Africa," he added.Malware outbreaks
Despite the threat, Kaspersky said that only 29.6% South African computer users faced local threats and 15.4% had to deal with web-based attacks.
"This places South Africa 130th worldwide when it comes to local threats and 141st in terms of web-related threats," said Saad.
The lack of internet penetration and cable broadband in the country are possible two of the factors that prohibit massive malware outbreaks in SA, but that has not stopped cyber criminals from following a specific modus operandi

Cyber criminals are known to follow a pattern of targeting the most popular platforms and users.
As Microsoft Windows became the most popular operating system, cyber crooks began writing viruses and worms to infect PCs. As a consequence of the mass migration to Android mobile devices, those smartphones and tablets are being targeted by criminals intent on stealing personal and financial information.
"There's no absolutely safe operating system at the moment. The more popular the software is, the more it is targeted by cybercriminals," said Saad.Myth
Apple users had long boasted that their machines were virus free but Saad said that this was a myth as Apple Macs were caught in a huge botnet.
"The myth about Mac OS security was demolished when in 2012 the quantity of created anti-virus entries grew by 30% in comparison with 2011, and notorious Flashfake Trojan managed to create the biggest Apple botnet which consisted of 100 million devices all over the world."
